We selected 24 physically and mentally healthy university students (12 male and 12 female) as the experimental subjects. The subjects were required to perform sustained attention to response task (SART) activities under the nine different lighting conditions and collected the alpha (α) waves (8–12 Hz) from the electroencephalography signals. Subsequently, the mean power spectral density of the α waves and various SART parameters were analyzed and tested. Finally, the effects of different CCT and illuminance levels on the subjects' attention were compared. With the increase in CCT, the attention level tended to increase linearly, whereas the attention level was the lowest at 300 lx and the highest at 500 lx and appeared as an inverted “U” shape. The subjects' attention level was the highest at the combination of CCT of 5300 K and illuminance level of 500 lx and the lowest at the combination of CCT of 3300 K and illuminance level of 500 lx.

For more than a decade, advancements in AR technology and their applications have been expected to revolutionise the manufacturing industry and deliver quality and productivity gains. However, due to factors such as equipment costs, skills shortages and technological limitations of AR devices, operational deployment beyond prototypes has been constrained. Real-world, usability studies can explore barriers to implementation and improve system design. This paper details a mixed method usability case study of an AR head-mounted display (HMD) to perform a short, simple visual inspection task. Twenty-two participants from South Australian manufacturing businesses inspected a pump and pipe skid while working at height. Overall, workload demands for the task were considered acceptable and just below the “low” workload threshold (NASA Task Load Index, mean = 29.3) and the system usability was rated “average” (system usability scale, mean = 68.5). The results suggest the task did not place too high a burden on users and was an appropriate initial exposure to AR HMDs, but further refinement to the interface would be desirable before implementation to minimise frustration and promote learning. Users were enthusiastic and open-minded about the AR HMD although results indicate that even with recent advancements in AR HMD technology, interactions between the task, technology and environment continue to cause human and technical challenges—some of which are relatively straightforward to address but others are dependent on larger-scale efforts.</p>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"33 3","pages":"272-296"},"PeriodicalIF":2.4,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/hfm.20986","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50133870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article reports on a validity study of the Net-HARMS method in which outputs were compared to an expert analysis developed by the first two authors of this paper, with review by subject matter experts. The findings show that individual participant performance was poor for both groups yet when both group's analyses were pooled, validity significantly improved. Further, a subject matter expert analysis of the false alarms identified by participants showed that they may in fact represent credible risks.

Hospital care processes ending in discharging older adults represent a major challenge, as a number of interrelated tasks or activities are involved in the processes. The functional resonance analysis method (FRAM) is used to identify activities that constitute a descriptive model of the discharge planning processes and to assign the completion time to each task or activity. Then the critical path planning technique is utilized to identify the critical path of the discharge process. To this end, the Program Evaluation and Review Technique (PERT) is employed. Published data regarding six older patients are used to examine the potential utility of the introduced method to improve the discharge process of older adults. The results show that the integration of the FRAM and PERT is able to identify the critical activities that constitute the critical path of the discharge process. It also helps analyze the completion time assigned to each task/activity and calculate the completion time of the discharge process. The probability of completing the discharge process within a target completion time is also discussed. The results add further evidence showing the applicability of the FRAM and PERT to scheduling systems for the discharge planning processes.

In this study, we assess changes in soft tissue stiffness in the upper arm of individuals under both dynamic (0.7 and 0.25 m/s) and quasi-static (QS) impacts under a constrained contact condition. Three impactor shapes (cylindrical, cubic, and spherical) are used in this study. Impact experiments are conducted using impactors attached to a pendulum. The soft-tissue displacement is determined using an ultrasound device. The impact force-displacement curves illustrate the nonlinear behavior of the soft tissue stiffness under both dynamic and QS impacts. By utilizing the <i>“Linear Mixed Model”</i> statistical analysis, we found that changes in the impact velocity significantly influenced the changes in the nonlinear behavior of soft tissue stiffness while there was no significant effect of the changes in the impactor shape on the nonlinear behavior of the soft tissue stiffness. Additionally, we revealed that the changes in the soft tissue stiffness are influenced by the size of the contact area. Moreover, we demonstrated a range of changes in soft tissue stiffness for different impact velocities, which provide valuable information for developing future validation test devices in HMI, such as the design and evaluation of dummy skin.</p>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"33 6","pages":"433-448"},"PeriodicalIF":2.4,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50138610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evacuation behavior, perceived urgency, and delay time were measured. Results confirmed the effect of redundancy on measurements, and participants complied better with the speech-inserted and technology-based alarms, but there were no differences in evacuation effectiveness between them.

The aim of the study was to analyse the relationship between explicit consumer experience and neuropsychological measures. A group of VI and sighted explored and manipulated three different product categories inside the supermarket, while EEG, behavioral and self-report data were collected. Electroencephalogram (EEG) findings showed a generalized delta band activity in pasta compared to frozen food and it was interpreted as higher emotional activation probably required by selecting the correct stimuli in a multisensory environment. A delta band activation was also found in frontal area in VI compared to control and it was supposed to be an index of greater cognitive control. Finally, higher delta band activity in parieto-occipital and temporal areas were related to greater sense of disorientation. In conclusion, it was found that VI experience grocery shopping more stressfully and with greater cognitive effort (parieto-occipital area) than people without visual disability. In general, VI use the sense of touch (temporal area) more and have more difficulties in orienting themselves internally in the store. The results could encourage the use of tactile touchpoints, braille maps, or an initial guided exploration of the supermarket, to allow the VI to memorize the internal layout of the different product categories and allow them to shop independently. Another suggestion would be to make products within the same product category more distinctive, perhaps by adding additional tactile information.</p>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"33 3","pages":"246-258"},"PeriodicalIF":2.4,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50144705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the AHP showed that management commitment, buffering capacity, and reporting culture were the most influential RE indicators. In addition, anticipation had the lowest impact on RE. The most important subindicators of the RE indicators were also identified using a hierarchical analysis through AHP.

However, existing studies have rarely investigated construction workers' comprehension of safety signs at construction sites. Moreover, existing evaluation methods are generally based on subjective behavior tests, questionnaires, and interviews. Therefore, this study examined the effects of semantic congruity on the comprehension of safety signs, including two sign types (prohibition vs. warning signs) and two conditions (semantic congruence vs. incongruence), combining event-related potentials and time-frequency analysis measurements. Adopting the S1-S2 paradigm, electroencephalogram data were recorded when participants decided whether S1 and S2 were semantically congruent or not. Results showed that the semantically incongruent safety sign-word pairs elicited larger N400 amplitudes and increased theta (3–8 Hz) power in 300–420 ms. The amplitude of N400 in the semantically incongruent condition of the warning sign-word pairs was more negative than that for the prohibition sign-word pairs, while there were no significant differences between the prohibition and warning sign-word pairs in the semantically congruent condition. A greater late positive potential (LPP) (550–750 ms) was also elicited in the semantically incongruent safety sign-word pairs, which was different from previous studies that observed larger LPP in congruent conditions. These results suggest complicated cognitive mechanisms of safety sign comprehension in construction workers.

We observed and coded 12 coordination processes (each from one crew) of handling simulated emergencies on a full-scope dynamic simulator in Tianwan NPP of China. By calculating the proportion of coordination breakdowns and referring to the subjective evaluation of instructors, these control crews (all male) were classified into two performance levels (high and low). To compare the coordination-behavior patterns between high- and low-performing crews, we conducted social network analysis based on the number and direction of coordination behaviors. By examining intracrew relations in team coordination, this study indicated that high-performing crews exhibited higher cohesion and more balanced behavioral patterns in team coordination than low-performing ones. By investigating coordination-behavior patterns from the hierarchical structure of relations in the team, this study revealed that high-performing crews exhibited higher degree of team autonomy and self-management among junior operators, as well as reactor operator (RO)-centered pattern, whereas the low-performing crews exhibited senior reactor operator-centered pattern. For researchers, the results advance the understanding of the team coordination mechanism in NPP control rooms during emergencies and enrich team coordination theory in process control industries from the network perspective. In practice, this study suggested that the team coordination training of NPP control crews might be centered around junior operators (especially RO), with focuses on facilitating information sharing and mutual assistance between junior operators and enhancing the awareness of active cooperation of crew members.
